Ultimately both cards aren't that amazing, but yes like it was said the GT 630 will beat the GT 610. There are a few reasons why the GT 630 will beat the GT 610 despite the same clock speeds.
The GT 630 has more cores in it compared to the GT 610, it actually has double the cores that the GT 610 has. The GT 630 is also using much faster memory compared to the GT 610 which helps with rendering. Lastly the memory bandwidth on the GT 630 is MUCH higher compared to the GT 610.
